Abstract

As air pollution from industrial and automobile emission becomes more and more severe, the personalized, integrated gas
sensor is desirable for everyone to monitor everyday's air quality as well as their personal health condition non-invasive. Such sensor
should have the desirable features like energy efficient, miniature size, accurate response (down to ppm level), and selectivity.
Traditional bulk MOX based gas sensor works in the temperature range of 300 to 400 oC, which requires large amount of energy
to power the heater. We here propose using graphene based field effect transistor as label-free sensor platform, to detect gas
selectively by measuring its electrical properties at room temperature.
